To all whom it may concern:

Be it known that we, FRANK Snonn, -THOMAS SHORE, and WILLIAM SHORE,subjects of the King of Great Britain and he land, the two former beingresidents of Rochdale and the latter of London, in the counties ofLancaster and London, respectively', England, en "neer, joiner, andmanufeaturer, res ective y, have invented certain new and uselIinprovements in Sash-Fas- Y which,

teners, cation.

This invention relates to fasteningfdevices for windows; and it consistsin the novel construction and combination of the parts hereinafter fullydescribed and claimed.

Our invention will be fully described with reference tothe accompanyingdrawings in of which the following is a specifi- Figure 1 is a frontelevation of one form of the .device forming the subject matter of ourinvention, Fig. 2 plan of same, partly in section, Fig. 3 side elevationalso partlyin section Fig. 4 detached sectional view showing the boltarrangement more clearly.

In carrying out this invention we secure on the inside face of one ofthe sash frames a, usually the top one, and at .one or both sides of thewindow a plate 6 having a numer of tapped holes- 0 arranged at suitabledistances apart, such plate being of any suitable length. Or in place ofit a number of se arate plates, tapped plugs or tubes, each aving onehole may be similarly secured. On the other sash, usually the bottomone, we mount a bolt at having at its inbolt passes through a net end ascrewed portion 6 usually of an enlarged diameter, ada ted toengage-with any of the tapped holes 1n the plate or plates referred to.The intermediate portion of the tubular bracket f freely, such bracketbeing directly pivoted on a vertical pivot g secured to the; sash frame.The tubular bracket may be pivoted on a foundation plate It secured tothe sash frame. The object of the pivoted tube, or it may be a pivotedstud with a hole in it, is to enable the screw (5 to be withdrawn fromany of the tapped holes in the late I) and turned about a vertical axisto e engaged with'or disengaged from a rack or slotted plate or a platewith holes in it, hereinafter referred to. The outer end of the bolt clhas a second screwed portion a on which is mounted a milled headedcollar 7' or a nut means y which it may be turned around on the bolt clwhile the outer end of the latter is provided with a thumb portion 70 orcross bar by means of which it can be operated for screwing into orhereinbefore described. The rack .or slotted plate m, previouslymentioned, is secured to the window frame a in close proximity to theside of the bottom sash, the slots 0 in it being open the screw boltreferred to, to be turned into or out' of each of the slots about thepivot of the tubular bracket or stud herelnbefore mentioned.

The operation of a device constructed as hereinbefore described is asfollows When the screwed bolt cl is. at right angles to the sash frames,as indicated in the drawings, and is screwed into one of the tappedholes 0 in the top sash both sashes are absolutely locked together andcannot .be moved up or down. They may be thus held in their closedposition, the bolt acting to this extent in -a similar manner to the oldfashioned screw used for securing windowsashes. If, say, it is desiredto lower the top sash it is only'necessary to unscrew the bolt from theplate 6 and pull it backward.

The top sash can then be freely moved up plate m secured to the windowframe. One

In either case the bottom out of'the tapped plate" end of the collar 7'bears against-the bracket f, and when the collar is screwed up againstthe bracket it causes the two sashes to nip the middle guide rib a ofthe frame, so that the sashes are prevented from rattling. If, howeverit is'desired to raise or lowerthe bottom sash the screwed collar isslacked back, the screw disengaged from the hole in the top sash, drawnforward and turned about the vertical pivot referred to so as todisengagethe screw and long boss of the collar from the slot 0 in thefixed bracket m.

The bottom sash cah then be raised or lowered to leave any openingrequired at its bottom end while the top sash is entirel closed orpartially open as before describe After adjusting to t 1e positionrequired the screw is turned about the vertical pivot into another slotof the fixed plate screwed forward into the hole in the top sashandlocked by the screwed collar.

It will be understood that the aforesaid means allow of either sashbeing moved independently and'looked in positlon securely I V whererequired but that in no case can the s litab curely lockedto prevent anyfurther movee extent and yet enable them to he sement either toward thetop or bottom of the window frame; The arrangement also enables thesa'shes .to be drawn ti htly together so. as to prevent any rattling 0the windows and. also permits of the usual window catches beingdispensedwith.

I What we claim as our invention and d'esire to protect by LettersPatent is Ina sash fastener, the combination. with pivoted to the sashwhich is arranged next adjacent ,to the said plate and frame, a

serewthreaded socket secured to the other sash, a revoluble locking-boltfor engaging with the said screwthreaded socket, said bolt bein slidablelongitudinally in the said brachet and having a screwthreaded portion,and a screwthreaded collar engaging with the said screwthifiaded portionof the bolt and movable with it pivotally into engagement' with the saidslotted plate.

In testimony whereof we have'hereunto the frame, a bracket set our handsin the presence of two Wit- HQSSGS- FRANK SHORE. THOMAS SHORE. WILLIAMSHORE. Witnesses:
